Application filed April 27, 1923. Serial No. 635,037.

This inventionV relates to diemachinesfor forming sheet metal handles for saucepans and the like; and has for its objects to provide a. machine including a beading die, in-

to which blanks are fed and aforming or shaping Vdie which automatically receives.

the partially finished product from lthe beadingl die 'and finally shapes the finished saucepan handle in lcontinuous operations as the product is .automatically passed through the machine.

The above and other objects may be attained by constructing a machine in the f manner llustrated in drawings, in whichchine in the open position, the lower die being shown in section; .w

Fig. 9, a section on line Fig. 10, a plan view handle; andr Fig. 11, a section on line 11-11,Fig. 10. Similar numerals refer to corresponding parts throughout the` several figures of the drawings. a

The lower dies 'are assembled upon the bedor base 1, which is mounted upon asuitable support and inclined at a considerable angle, as shown in Fig. 1. The forward or vraised end portion ofthe bed is provided with the platform 2, upon its upper face, and the rear end of the body is provided withthe longitudinal channel 3.

` The lower beading or folding die includes a central, longitudinal ribA 4 mounted upon the platform 2, and a pair of slidable, elongated blocks 5 mounted for transverse movement toward and from each other within the guides 6. o

The blocks 5 are normally held in the 9%9, Fig. s;

of the finished the accompanying Figure lis a sideelevation ofthe` inaopen position, in engagement with the posts 7, by means of the `spiral springs 8l which are connected yto thepins upon the blocks 5 and to vthe pins 1() connectedto thebase.

or other stationaryportion ofthe machine.

Asbest shown in Fig. 8, itfwill be seen'V Y thatthe inner edges ofthe blocks 5 are prol vided with the ribs 11 registering withj the central rib 4; andwith the half round longitudinalrgrooves 12 just above said ribs. 65.

rlhe outer longitudinal edges of the blocks 5 are chainfered or beveled as at 13 and trans-v versely disposed guide plates llfare fixed to the upper faces of the lblocks and extend outwardly uponeach side, being provided 79 with the guide openings 15. l

The inner,` longitudinal edges of the blocks 5, as shownin Fig. 2, are slightlyv inclined toward each other from front to rear of the machine, this being for the pur-,` 7.5 posehof limiting the movement of the blank as it-slides downward into position, the front end of the blank engagingfthe edges of the blocks 5 and being held in position to be beaded.l f

A channel. guide 1 6 is mounted kat the forward end of the platform 2 .and provided with the rearwardly tapered flanges 17 and the downturned outer lip 18, to facilitate the insertion of the blank shown at 19. This blank is .formed upon anotherfmachine which cuts the blank to the desired size and shapes and punches vthe opening 20 in one end thereof and bends the longitudinal edges upward at an angle as at 21. v

The lower shaping die is mounted in the groove or channel 3 and comprisesthc forward portion 22 taperedv downwardly and rearwardly toward the inclined channel portion 23 provided with thecentral, in- 95 verted 'V-shaped rib 24 which terminatesv in the substantially vertical shoulder 25, the rear portion 26 of the lower shapingdie being inclined gradually upward and rearward from said shoulderA andA slightly curved throughout its length, terminating in the upturnedend 27. 1,-

Each o f these parts of the die is preferably separable yas best shown in Fig.V` 5, the several members being fixed in the channel 3 by means-of a set screw 28 extended through the rear flange 29 of the base and engaging the rear end of the die. A knockout punch 30 is preferably provided intermediate the ends of the lower shaping die to automatically remove the finished handle fromthedie,` i i f The upper or movable part of the machine includes the head 3l mounted forre-v ciprocating motion towardeand from the lower dies in a line perpendicular to the normal plane thereof and carries the up' per clamping and shaping dies, which co5- operate with the lower beading and shaping der side of'the'head as by` the-hangers 33.

A spaced pair of cam members 34vv depend*- ingv from the under wside of the head 131 in position'to 'engage the beveled edges lf3 ofV the blocks 5 to slidethe same transversely Y ytoward leach other is shown in Fig. `r3.

Av pair 0f depending lingers 35 are carried bythe head 3l, between the cam inembers 34 and provided with enlarged yhead portions 36 arranged Eto be received through the openingsfll o f'sthek guide vplatesI 14, to

Y assist in moving the blocks 5 back to the normal position, as the head/ is raised. The ,upper forming die comprises a block indicated A"at 37, the under side of whichV isy shaped to conform to `the upper surface of the lower shaping die, Y'and 'is provided with a pair ofspaced, depending plates 3 8 toco- Shlarng dieoperate with the'V-shapedrib 24 of the lower 'A' guide is formed to convey theI partly finished product from the heading die to the shaping die, and comprises a pair of blocks 3 9 mounted upon the basebeyond the beadr ingdie 'and provided with overhanging flanges 4 0 beneajtlrk which the blank is con` veyed to the shapngid. L

A guide lug 4l is` mounted upon onel side of the channel portion 23 of the lower form-y ingdie and upon the other side thereoffis mounted a linger '42V provided'with a 'Iset screw 43, arranged to remove the finished handle from'thefupper forming die inthe eventthe handle adheres thereto when the upper die is raised.- Y

In operating they machine, a blank 1 9 as shown in Fig. 6, is dropped into position through the guide land between theblocks 5 of the lower beading die,fthe end of the blank engaging the iIiCliIlCl edge portions of the blocks.

As-the head is depressed, the blocks 5 are moved toward 'each other byv ineansjof the Camskhthe. bentedge PQftOnS 2l' of th blank facilitating the folding or beading of the Same. as the die blocks are broughttogether as shown in Fig. 3, rolling orbead-` ing eahedge portion of the blank as shown at 44, l

As thehead ascends, the 4die blocks 5 are lmoved `back' into the initial position by "'.meansof the springsgS, thegfingers 35 assuring a positive movement of these blocks in `Ithe event the partly finished product should become wedged.V As Vthe Yproduct45 is released, it willfslide rearward and downward throughthe guides 38 until the end thereof ngages the stop 46 of'the lower shaping 1e. v Y

With theneXt descent ofthe head 38, the` upper yshaping die will engage the blank and Vcooperate with the lower shaping die tov forni the-finished handle 47shown1in Figs. 10 and 11, forming the angular 'end portion 48 for attachingthe same to the sauce pan, and

the lreduced, neck portionV 49 having the reint' forcing rib 50 for strengthening the same.

'Y It will, of course, be understood that with Veach descent" of the head two complete operations will be performed, asa blank will befbe'aded inthe beading dies and the `partly finished product will be' simultaneouslyshapedv shaping dies.

I claim:- j' 1 .A Yl. A"naehine of the character described Vinto a complete handle inthe including. a lower shaping diehaving -a V: Vshaped channel portion provided with flatv forming the partly completed product Y upper. edges to receive a blank and aninvertedV-shaped rib in' the channelk portion anda downwardly and rearwardly inclined portion and anupperdie cooperating therewith and having a' pair of spaced plates for engaging a sheet metal blank resting upon said fiat edges/to stretch the same over the' rib and into the channellof the lower die,

1 and an inclined portion 'to cooperate with the inclined portion of the lower die to form an angular end upon the nished product.

2. A machine of the characterddescribed including a stationary base anda movable head, a lower beading die carriedin the, base, an upperv clamping die cooperating therewith and carried in `the head, a lower shaping die'in the base having a V-shaped channel portion provided with fiat upper edges to receive a blank rand an inverted V-shaped.

rib in the channel portion and an, upper shaping diein lthe head cooperating with the lower shaping die and having a pair of spaced plates for. engaging a sheet metal blank vupon said flat edges to stretch ythe same over therib and into the channel of the lower die."v Q 'i Y In testimony that I claim the above, I have Vhereunto subscribed my name.y i
